I downloaded the ANT agent and the communicator a few weeks ago for my Forerunner 410. Since then I've had to bring out my old edge 305 because my edge 500 died and had to send back for warranty. I have two laptops with Windows 8 and both 64-bit. It didn't work on my laptop with the 410 software so tried on the other laptop. My other computer recognized the Edge 305 and was able to upload the new acitivites. I hadn't thought about it being a 410 issue so I downloaded the ANT and communicator plugins. Now my edge 305 is not being recognized on either computers. I tried removing the communicator and ANT Agent, but I'm still not having any luck.
Ok, so I have come to the conclusion that since the installation of ANT software my other Edge devices have become useless. I know this because I have two laptops. My main one already had the ANT on it and couldn't use my Edge 500. I then went to my other laptop and it recognized it and uploaded just fine. I then made the mistake to upload the ANT Agent, not knowing it was causing the issue, and then I had the same issues. I finally decided to reformat my laptop to new and uploaded the Garmin Communicator. I was able to upload from my Edge 500 and 305 after reformatting the computer, so I'm assuming there is a file conflict from the ANT Agent. I even tried to uninstall the ANT Agent, but still no help. What could it be....help!!!! I don't want to have to reformat my other computer? Thanks!
